Abstract
A plug-in ground fault interrupting type circuit breaker includes a resilient jaw (42) for engaging the neutral bar in a loadcenter. The jaw is formed at the end of a conductive strap (70) which passes through the window of a transformer (78) and terminates in a screw terminal (28) for attachment to a neutral load conductor (29). The phase conductive path also includes a conductive strap(80)that is coupled at one end to a phase load conductor terminal and at its other end to the breaker trip mechanism(24') The transformer and both strap conductors are mounted to a printed circuit board that is included within the breaker housing. The invention eliminates the separate pigtail for connecting the load neutral conductor to the loadcenter neutral bar.
